    I am not a fan of stacked beams, but this build is amazing, instantly recognizable. I also admire the video presentation You made, we start to catch up Top Gear in quality. Top notch work!

    Looks already very cool, following the progress!

    Sure it must be tested, I also build in LDD and also in real life paralell. For now I trust in my experiences, and also collecting by digital design the pieces I need to order (saving post). I made some improvement, now the rubber connectors are connected to a kind of torsion bars along the sides of the bottom 5x11 frames assembly. These end on both sides with 2L friction pins - thus increase the resistance for rotation. Let's make it open source, though I reserve the rights to control the design. HERE is the V1 file, equipped with Tumbler tires for scale. Some pins can not be placed for some reason, but I am sure they must fit. The build is very symmetrical, axles are almost identical. Drivetrain and differential is still a sketch, I will model the engine next. Modules are groupped for easier handling.

    For discussing legal and illegal build, please go to "Purism" topic, thanks. Yes, I checked that, due tu the angle, this issue is always there. On the other hand, You need to consider the sides as rigid pieces, fixed quite well on both ends. Also as the connections are in angle in the middle in each way, the forces which occure, are divided into X, Y and Z directions. Considering the torsion and friction of the pieces, probably You can separate with effort, but my guess is, that the frame will not fall apart that easily. We will see...

    I forgot to comment this. Thanks again @Erik Leppen and @Didumos69 for thinking with, I really appreciate! This solution offers the perfect rigidity, I will keep that as Plan B for sure! @Offroadcreat1ons Correct, Ariel is definitely inspiration for this, and also this toy here: Found another version for the connection problem, This is 100% legal, there will be some flex, but I think it is a nice compromise for look and rigidity. 2 rubber connectors between the middle frame and the lower "tubes". Downwards the upper "tubes" help to block the movement, upwards the rubber itself compresses to limit.

    Glad You like it! I need the space for the drivetrain axles in 5L width. My plan is to use center differentials and the force distribution happens on each side (left and right), instead of usual mid-axle diffs. You might ask why? Because it is a concept. Yepp, the stiffness must be tested in real life, till I get the required parts, I will leave like that, as it fits visually perfect. Thanks for the perspective, I think the same here.

    So, let's make a follow-up for this build. A bit background story of this project. I have 42000 wheels laying around for years, and really wanted to use them somehow. I also wanted to give try to build a concept car, but in a very purist way, focusing on joy of driving. This is the reason of the topic name: C.D.E. = Concept of Driving Essence. This will be a lightweight one person fun machine, not focusing on usual supercar features, rather testing conceptual designs together. What is planned: Monocoque frame - done 4 wheel drive / 2 wheel drive with gearbox - 50% 4 wheel steering / 2 wheel steering with gearbox - 50% Manual Modular build - done... yet No normal gearbox planned Don't expect beautiful curves, spoilers, high speed, it will be a tool, or better phrased: a go-kart on steroids. I built a lightweight V4 engine for it, planned to be placed behind the seat. Suspension is easy to adjust - also in strength and also in height. We will see how it works in real life (I expect reaching the finish line in summer or end of summer). Here is the start, first I wanted to place the engine on the right side, and the driver on the left side, but the curved framework grew on me, so I decided to go on that way. This is the actual status: And the result of today's brainstorming, the new monocoque frame: Let's cross the fingers, that everything will work. Every suggestions are welcome!

    Great, thanks Erik! I will test it as well. Meanwhile I made up THIS, could also work, pity I don't have all the parts yet to test. What do You think Gentlemen? It relies more on part-blocking-part, and not on connectors, but at least it fits into the concept visually. EDIT: Framework welding is ready, I think I should give a try for this solution on live build. I guess I should turn this topic into WIP now...

    Thanks Guys for the prompt support! I tried some versions, but there is always a minor offset. @Didumos69 Might be something, I will look into that, thanks! HERE is an extended LDD file for more creative freedom. Shown parts to be connected:
  10. agrof
    I could live with slight offset (this for is the solution the lime beams), but I would like to give a try to find a proper legal solution. So, no, the sides with the angle 3 connectors may not endure pulling. EDIT: I misunderstood it sorry, the sides must be strong, the model must be able to lift it by it, so yes, must endure pulling and pushing. I tried replace the Nr3 connectors with these parts already, of course it works, but I don't like the visual outcome at all, see below a comparison picture. Lime beams represent the illegal connection here too. To make it more understandable, it will be a monocoque frame for a concept car. The gap to bridge is maybe 0,25-0,3 studs.
  11. agrof
    It is a segment of the whole build. Red assemblies: no touch, no rotate, fix in space. All other parts can be deleted, replaced, whatever. Goal is, to connect the red assemblies (2x sides and middle one) together in a rigid and clean way. The lime beams do that, but it is an illegal connection, as they pull the side red assemblies inwards in real life, which will cause stress in the whole structure. If You check the picture closely, You can observe the black pins are in conflict with the ends of the lime beam. I hope this makes the task clear.

    Hello All, I am working on a new MOC, which for I am experimenting a lot with unusual pieces in Technic. To achieve their proper implementation into the Technic world, I am at crossroad now: wether to build illegal (tiny stress) or find a legal solution. I prefer the illegal version in look and strength point of view - I can deal with slight bend of the connected parts, but of course a legal solution would be nice - I have 2 for now, but they just look to messy, and 1 of them is weak too (only rubber connection). Lime 15L beams on the RIGHT is the illegal, the others on the LEFT are legal, only 2L axles missing from rubber connectors (marked with pink): Hereby I would like to ask the community for brainstorming, parameters to follow: All red parts must be on place - no possibilities to move. Axles in the frame pieces to be rotate freely. All red parts must be fixed horizontally and vertically too, rigid connection needed. Must be buildable in reality too. The solution must look clean, visible part of the MOC. HERE You can find the LDD file - some parts will be dropped at open, as it was made in Developer Mode, please refer to the picture above. I hope You will find interesting this problem solving, I am open for any ideas. Thanks for everybody in advance!

    Joint to the chor, really nice sculpting, and live alike illusion. Great MOC!

    If You can wait a bit more, than the new 60158 set might bring a solution for You (I am not sure if it is the same yellow, but looks minifig yellow): Hint: old Bionicle sets are full with black 3L pins, I bought 6-7 years ago ~9 kg Bionicle for cheap, and still live from it... many useless pieces, but tons of good one.

    I am a silent follower of this topic, and must say: I admire Your work with this. I am just wondering if bigger cylinders (V1 or V2) wouldn't be better choise for the grabber, as they can react smoother than the small ones - so the goods wouldn't spring out of the cage, in case. I see place for them in the picker frame, of course with different layout and pivot points. Maybe they could be fixed on the edges of the "triangle" frame.
  16. agrof
    I am speachless. What a bodywork... Can You present the rigidity of it as well, please? It is a pity on the other hand, that it is so well covered, that nothing can be seen from the not less interesting chassis - which I like a lot, actually even more than the bodywork.
  17. agrof
    Nice start, I would also rethink the hood, as the long panels stick out a bit. I would say, now you have a good sketch model, the next task is to fix all parts properly in a buildable way. Best way to check this, grab and lift the model just like a kid would do, and it may not disconnect. You can expect a long process, but precious learning time, with rewarding finish. For me it took 1 year to get from here... ...to here, with way over 15 (I gave up to count at this stage) rebuilds from zero: Okay I am lazy too, and I gave him rest for couple of months. And meanwhile the flower passed away unfortunately.

    Agree, everyone does it in own way, I found my challenge in using official parts only, but like to follow and anlyse all of the ideas around. No complains recently about if it is illegal, or non purist, can be considered as increase of general tolerance too. I would put my thinking on these. I don't think it is ludicrous, because the key factors for parts are: availability and quality. New parts from TLG becomes widely spreaded in a well known high quality, thus anyone has access to them. Same is true for third party strings and tires, and also for stickers nowadays (not to mention: stickers are always just nice visual add-ons, but not structual and essential parts). They are easy to get in superb quality for a wide audience. What differs 3D printing from this? It is still in it's cradle, still too expensive, still not nice enough, still not easy to get, also needs quite some additional equipment (software and hardware wise too). I see time will come when it can be part of daily LEGOing, but in a far distance. Of course some hardcore fans can make this into a religious debate, and don't forget, there are even extremists, who just don't consider Technic as LEGO. So there are definitely levels of engagement towards parts usage, all of them has the own ideology, audience, but most importantly: all adds value to the whole universe of BUILDING. "Studded or studless. All to build you have to."

    After creating some MOCs, and built them both digitally and real, I realized that I am purist, although I am friend of third party tires. First of all: just like @Erik Leppen wrote, much more fun, and keeps the mind busy in a challenging way, than find a third party workaround (like 3D printed parts) - feels like giving up, only exception is maybe experimenting. Many times I feel with 3D printing, that the parts are so specialized for one purpose, that it could be called Playmobil, or other non-buildable toys... If I build a MOC, I am here in the forum not only to get, but also to add value, see: to share it. If I share, than it must be able to be built by anyone - purists, non purists, children, adults, whoever has widely available LEGO parts. If it is buildable, it must be as solid as just possible - no tricked or poor connections. Also buildability and optimization of the parts are another important aspects, and make a project complete for me. (Remove unnecessary parts, less color variety, so once one needs to place a Bricklink order for that MOC, than it is more effective) All in all: my main drive is, that anyone should be able to enjoy the build as much as I do. I learnt a lot since my buggy - with wich I was not completely sure to share first, as I did not found it good enough. Meanwhile I checked couple of MOC reviews, and I realized, that damn, it is just as good, or even better - as it doesn't falls apart by a single touch. But I hinted the weak points as well, I feel it is the correct way. Some might be able to improve (and it happened luckily). That's why I really appretiate the WIP topics, although I am a lonely loner on a lonely road... alone (design-wise), others can offer creative and fresh solutions for a problem, coming from a different point of view - still by using LEGO parts only. Still, I like to use the material and structural properties of LEGO parts, example: using axles as torsion bars for suspensions, or using LEGO tires turned inside out in system builds or at buildable figures. Can this be done without injuring or creating permanent deformation in the part? Use it! This is the art part of / with LEGO for me, I don't consider them as MOCs, and yes, some of those are real ART.

    Seen it!

    Yes, although I really like the 42070, the price is really hard to justify. I will wait with final conclusions, but for the moment I feel like there is a 7 more and a 0 less indicated in that official price. Or at least one more XL motor is missing from the part list... Let's make a quick theoretical analysis, I just checked the replacement part order at LEGO - prices converted from HUF to EUR: tires (x 6), rims (x 6) and the gear racks with housings (x 4 each): 58,66 Euro electronics (1 XL; 1 M; 1 IR receiver; 1 IR controller): 63,31 Euro panels approx (36 panels counted quickly): 40 Euro portal axles with gearblocks (x 6 each): 11 Euro This is 72 pcs, which take 172,97 Euros from budget. 97,02 Euro left for 1790 parts (5,42 cents per part). Now, assuming, that LEGO put extra profit on replacement part orders due to extra storage, handling, administration, labour costs, the production costs and due to the selling price in packed products should be less, so the above mentioned 72 pcs should be counted with less amount. I want to say with this: I don't know where this calculation goes, but I definitely did it.

    via: https://www.facebook.com/BuildingQuality/ Edit: there is some more stuff in the trunk, looks like a shelf/desk to be pulled out, and to erect.

    I think, the overall shape skeleton of the car is really spot on (! ), though I strongly recommend to keep on working on it, and to work out the details too. Now it is half baked, I know it is easier to start with a new project - but will be that finished on halfay too? I am worried, if you just step further, than you will not improve yourself in terms of steadfastness of purpose. If you are not satisfied with the result of this, than just start over again, and correct the things you want. It is the harder way, but much much more rewarding in the end.

    Do the designers build AFOL's MOCs - for brainstorming or just for fun (privately)? What is the minimum batch quantity to run a part in production? As the moulds are usually multiple nested, better to formulate this way: what is the minimum batch quantity to run a mould in production? (5000-10000 moulds in minimum 5 hours cycle?) How much is the set-up time for a mould in production (0,5-1 hours)?

    Great to see it finished, thanks for the extra effort with the pdf instructions!
